Distortion / Saturation
Parameter Value range Unit Description
Type
OD, DS
Choose between two methods of effect generation with different
characteristics: OD (Overdrive) and DS (Distortion). While Overdrive
models the characteristics known from tube amplifiers, Distortion
provides the distortion characteristics typical of transistor amplifiers.
Drive
0-100 %
This parameter controls the intensity of the effect (scaling up
frequency amplitudes).
The values range from 0% (linear) to 100% (max. drive amount).
Frequency
250Hz - 8kHz Hz
This parameter determines the frequency spectrum that is affected
by the chosen effect type. If you prefer to saturate only the lower
end of the frequency spectrum, set the desired filter frequency for
the underlying low-pass filter with a transition steepness of 12 dB.
Post Gain
(-∞) – 0 dB
Adding this effect type will considerably amplify the output signal.
With Post Gain, you can attenuate the mix again at the output
channel. The values range from --∞ (mute) to 0 (min attenuation).
Chorus
Parameter Value range Unit Description
LFO-Wave
Sine, Triangle
Determines the displacement waveform of the underlying low
frequency oscillator (LFO). This is a control curve outside the audi-
ble spectrum of human ears (below 20 Hz, see also modulation
rate). With the waveform, you can give the effect distinctive
characteristics. Sine produces smooth characteristics, while triangle
is known for sawtooth-like sound characteristics of the delayed
duplicate.
Rate
0-10 Hz
Controls the speed of the LFO displacement and thus the speed of
the fwavering sound. This parameter controls the length of the
period of the LFO waveform.
Depth
0-127
Controls the intensity of the effect by adjusting the height of the
LFO amplitude. The parameter values range from 0 (off) to 127
(intense).
